The materials and mechanisms of a wind turbine, exposed to winds and bad weather, are subject to solid physical constraints. Parts eventually wear out and become brittle, reducing machine performance and safety.
According to the Environment and Energy Management Agency (ADEME), the lifespan of a wind turbine is estimated at 25 years. Beyond that, the technical reliability and efficiency of wind turbines start deteriorating.
In an individual wind turbine owned by an individual (generally smaller in size), the lifespan can differ from 20 to 30 years, depending on the manufacturer.

Factors affecting the life of Wind Turbine
Though ADEME has given a wind turbine lifespan of 20 to 30 years, this duration may vary depending on certain factors. These factors may cause faster wear of components or ancillary installation elements, such as the inverter, batteries, the meter, or electric cables.
Due to sea air, vibrations, frost, or even lightning, Corrosion can cause the structure to wear more quickly. The common factors affecting the life of wind turbines are:
1. Fire
Fire can cause a total loss of wind turbines when a unit is completely consumed and cannot be repaired.

2. Extreme weather conditions
In some circumstances, the weather is responsible for problems – sometimes, the strong winds are too much for the machine to withstand. Brake failures and upturned blades make things even worse.
3. Problems with the paddles
The leading causes of problems with the blades are lightning, damage from collision with objects, poor design, poor material. Accumulation of insects, oil, and ice on the edges also reduces efficiency by up to 40% less.
4. Bearing Problems – The Achilles Heel of Turbines
No matter the turbine model, bearings are always an issue in all of them. The main reason for bearing failures is the peeling of the surface visible to the naked eye.
5. Miscellaneous factors
- Failure to comply with recommended maintenance practices in lubrication procedures, collector systems, etc.
- Bearing mechanical or electrical failures, rotor failures, cooling system failures leading to excess heat and, in turn, fire.
- Misalignment or other improper installation, excessive vibration, voltage irregularities, converter failure, improper grounding, and excessive speed (which leads to bearing problems).
- Manufacturing problems include loose components, inadequate electrical insulation, rotor failures, other sections inside the machine that complicate service, etc.

Ways to extend the life of wind Turbine
We can extend the life cycle of wind turbines to 30 years with timely and proper maintenance. Proper repairs are also essential for generator reliability and longevity.
The other ways to extend the lifespan of your wind turbine are briefed below. These precautions are essential for your wind turbine’s safe and efficient use.
1. Protect the wind turbine from lousy weather
It may seem paradoxical, but the wind is not always the friend of the wind turbine. Too strong winds affect its proper functioning and can even seriously damage the installation or cause a breakdown.
If a storm is a forecast, plan to orient the blades to limit the gusts’ impact or block the edges using a mechanical brake system. If not, have time to act beforehand; checking the apparatus before restarting is preferable.
2. Monitor the weak signs
The slightest sign of weakness (suspicious noise) should alarm you and prompt you to do a thorough check. Even the slightest sign of weakness could cause cascading problems to other parts of the wind turbine. At the modest defect, repairs and changes of components are necessary.
3. Life extension
The manufacturer of wind turbines has developed an alternative scheme to certify the longer utility life of wind turbines. It consists of analyzing the turbine before it is 20 years old and changing the necessary components to function for a few more years.
4. Boost wind turbine performance through structural monitoring
To track performance problems and malfunctions of a wind turbine requires monitoring and one solution is to use a digital twin. Digital twins have essentially computerized companions to their physical counterparts.
In wind turbines, a digital program reflects what its physical twin does as it operates and generates power. It captures all data from operating turbines, analyzes it, and provides real-time information based on data it receives.
The monitoring system helps identify underlying problems that we may not have identified previously. The types of issues detected can include performance, turbine health, and identification of the remaining useful life of an asset.
